Linux system Apache service configuration tutorial.

The tutorial for configuring the Apache service on a Linux system is as follows:

Step 1: Install Apache

First, log in to your Linux system as root or a user with sudo privileges.

Use the following command to install the Apache service:

sudo apt updatesudo apt install apache2

Step 2: Start Apache

After the installation is completed, the Apache service will start automatically. If it does not start, please use the following command to start it manually:

sudo systemctl start apache2

To make the Apache service start automatically when the system starts, use the following command:

sudo systemctl enable apache2

Step 3: Configure Apache

The main configuration file of Apache is located in the
/etc/apache2 directory.

Open the main configuration file using the following command:

sudo nano /etc/apache2/apache2.conf

In this file, you can perform various configurations, such as modifying the default port, setting up a virtual host, etc.

Step 4: Configure virtual host (optional)

If you plan to host multiple websites on Apache, you can configure virtual host.

In the
/etc/apache2/sites-available directory, you can create a new virtual host configuration file. For example, use the following command to create a virtual host configuration file named
mywebsite.conf:

sudo nano /etc/apache2/sites-available/mywebsite.conf

In this file, you can configure the relevant information of the virtual host, such as domain name, website root directory, etc.

After completing the configuration, use the following command to enable the virtual host:

sudo a2ensite mywebsite.conf

Then reload the Apache configuration:

sudo systemctl reload apache2

Step 5: Firewall Settings (Optional)

If your Linux system has a firewall enabled, you need to allow HTTP (port 80) and HTTPS (port 443) traffic through the firewall.

Allow HTTP traffic using the following command:

sudo ufw allow 80

Allow HTTPS traffic using the following command:

sudo ufw allow 443

Step 6: Visit the website

Now you can access your website through your browser. Enter the server's IP address or domain name in the browser to access the default website or configured virtual host.

The above is a tutorial for configuring the Apache service on a Linux system. Please make the necessary configuration and modifications according to your needs.
